Some guy falls down the stairs, gets a head injury, tries to drive home, zones out in the parking lot in his car, and when a disoriented man does not respond to police orders, he is tased repeatedly, then wrestled to the ground, handcuffed, and dies (see here and here).
It’s clear that Tasers should be legally as a lethal weapon, because the police use them irresponsibly and with impunity because, unlike other potentially lethal force, there is no review board following the use, unless there is a death.
